Description

[Detailed Description of the Invention] <Field of the Invention> This invention relates to an article aligning device that aligns and brings out a large number of articles to be sorted, such as electronic components, stored in a hopper in a single column.

<Prior art and its problems> Conventionally, as this type of alignment device, for example, the fourth
The one shown in the figure is known. In the figure, 1 is a hopper that stores a large number of articles to be sorted, and 2 is an article lead-out pipe.This pipe 2 is slidably inserted into a supporting cylinder 3 provided at the bottom of the hopper 1. A passage 4 within the container 2 is an article lead-out passage for sequentially leading out the articles 5 to be aligned one by one in a predetermined orientation.

In the above configuration, the pipe 2 is lowered from the position indicated by the imaginary line to the position indicated by the solid line, and the upper end opening 2a of the pipe 2
Immerse yourself inside. At that time, the objects 5 to be aligned around the pipe 2 move into the space formed after the pipe 2 is lowered.

Of these moved articles 5 to be sorted, only the articles 5 to be sorted that have taken a posture in a predetermined direction are taken into the article lead-out passage 4 one by one from the upper end opening 2a of the pipe 2 and lowered, and the same operation is carried out thereafter. Repeatedly aligning the articles 5 in the hopper 1 into a single column,
It is led out to the outside as an aligned article 5a.

However, when the pipe 2 is raised from the lowered position indicated by the solid line to the position indicated by the imaginary line, the upper end opening 2a of the pipe 2 pushes up the articles 5b that are not in the receiving position, damaging the articles 5b or causing damage to the articles 5b. There is a drawback that the articles 5b to be aligned block the article outlet passage 4.

Further, as another example of this type of alignment device, the one shown in FIG. 5 is conventionally known.
In the figure, 1 is a hopper that stores a large number of articles 5 to be sorted, and 6 is a rotary table set in the hopper 1. On the outer periphery of the upper surface of the rotary table 6, articles 5 to be sorted are placed in a row one by one. A circular groove portion 6a is formed for storing in columns. Reference numeral 7 denotes a chute for guiding the articles 5 to be aligned in the groove 6 to the outside as aligned articles 5a, and the chute 7 is set along the tangential direction of the groove 6a in correspondence with the groove 6a.

In the above configuration, when the rotary table 6 is rotated clockwise (in the direction of arrow A), the articles 5 to be aligned on the rotary table 6 are moved toward the outer periphery of the rotary table 6 by the centrifugal force and stored in the groove 6a. be done. The articles 5 to be sorted stored in the groove 6a are transferred into the chute 7 from the tip opening 7a by rotation of the rotary table 6, and are led out of the hopper 1 as articles 5a arranged in a single column.

However, the articles 5b to be aligned, which are not in the reception position of the chute 7 on the rotary table 6, are pressed by the subsequent articles 5 to be aligned stored in the groove 6a and transferred by the rotary table, and are pushed away from the tip of the chute 7. There is a drawback that the articles 5b to be aligned may be damaged by colliding with the opening 7a, or the article lead-out passage 4 may be blocked by the damaged articles 5b.

<Purpose of the invention> This invention was made in order to eliminate the above-mentioned conventional drawbacks, and provides an article sorting device that does not cause damage to the articles to be sorted or blockage of the article delivery passage by the articles to be sorted. is intended to provide.

<Structure and effects of the invention> The article aligning device according to the invention includes a fluid that injects pressurized fluid into the hopper through an article lead-out passage set at the bottom of the hopper that stores a large number of articles to be sorted. In addition to providing a passage, a regulating body is provided for regulating the amount of stacked articles to be sorted in the hopper, and a floating space is formed in the regulating body for floating the articles to be sorted by pressurized fluid. It is said that

Therefore, according to this invention, the stacking amount of the articles to be aligned stored in the hopper is regulated by the regulating body at the portion facing the pressurized fluid jetting part, and the stacking amount of the articles to be aligned is Since the floating space is formed by the regulating body, the articles to be aligned are floated within the hopper by the jetting of the pressurized fluid.

The objects to be sorted, which have become in the receiving position due to this floating, fall one by one into the object lead-out passage under their own weight.
They are arranged in a single file and led out of the hoppa.

In this way, the articles to be sorted in the hopper are floated by the pressure of the pressurized fluid, allowed to fall by their own weight from the article outlet passage, and guided out of the hopper. is reduced by the pressure of the pressurized fluid. Therefore, the mechanical impact force applied to the items to be aligned is reduced, and there is no risk of damaging the items to be aligned.

In addition, since there is no risk of the items to be aligned being damaged as described above, there is no risk of the outlet passage being clogged by the damaged items, and even if a phenomenon that causes clogging occurs, the above-mentioned Since the pressurized fluid is injected into the article lead-out passage, the fluid pressure can always eliminate the clogging phenomenon of the articles to be aligned, and it is possible to achieve a reliable alignment operation of the articles to be aligned. .

<Description of Embodiments> Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 1 is a sectional front view showing an embodiment of the article aligning device according to this invention. In the figure, reference numeral 11 denotes a hopper for storing a large number of articles 5 having approximately the same external shape.
The bolt 13 is fitted into the bottom of this cylindrical body 12.
and a bottom wall 13 having a funnel-shaped bottom surface 13a fixed at c.

Attachment hole 13 formed in the center of the bottom wall 13
In b, the items to be aligned 5 are placed in a predetermined orientation.
An article delivery pipe 14 formed with an article delivery passage 15 for sequentially leading out articles one by one is fitted. The article lead-out passage 15 is formed with an opening end 15a that opens into the hopper 11 and widens toward the end.

The article outlet pipe 14 includes an article outlet passage 1.
A fluid passage 17 for injecting pressurized fluid D is formed in 5 . The fluid passage 17 is directed obliquely upward so that the pressurized fluid D is injected into the hopper 1 through the article outlet passage 15.

Further, the lower end of the fluid passage 17 is communicated with an inlet 17b for pressurized fluid D through an annular fluid passage 17a, and the inlet 17b is set at the lower end of the article outlet pipe 14. An annular passage 17a is formed in the cover 16 and between the article outlet pipe 14 and the cover 16.

18 and 19 are seal rings, 20 is tube 2
The passage 22a of the tube joint 20 is arranged coaxially with the article outlet passage 15 through the suction gap 22.
The tube joint 20 is connected to the intake gap 2.
As shown in FIG. 2, it is fixed to the article delivery pipe 14 via a spacer 23 for forming the article 2 and the cover 16 with bolts 24, as shown in FIG.

Reference numeral 25 denotes a regulating body disposed facing the spouting part M of the pressurized fluid D in the hopper 11. The regulating body 25 is a cylindrical body disposed approximately coaxially with the article outlet passage 15, and has a flange portion 25b. It is fixedly supported by a screw body 27 to a bracket 26 installed above the hopper 11 via the screw body 27 .

The regulating body 25 includes a lower end portion 25c of the cylindrical body 25a.
and the bottom surface 13a of the bottom wall 13 of the hopper 11, the pressurized fluid ejection part M in the hopper 11 is
A floating space C is formed inside the cylindrical body 25a to regulate the stacking amount of the articles 5 to be aligned and to float the articles 5 to be aligned by the pressurized fluid D. In addition, 28 is a lid body of the hopper 11, 29
is the knob.

Next, the operation of the above configuration will be explained.

Now, due to the gap 27 between the lower end 25c of the cylindrical body 25a in the regulating body 25 and the bottom surface 13a of the bottom wall 13 of the hopper 11, the stacking amount of the articles 5 to be aligned at the pressurized fluid spouting part M in the hopper 11 is determined. Since the space C is formed inside the cylindrical body 25a, when the pressurized fluid D is injected from the fluid passage 17 through the article lead-out passage 15 into the hopper 11, the The article 5 floats within the hopper 11 as shown in FIG.

As a result of this floating, the articles 5 to be aligned have changed from the solid line state in FIG.
The articles fall one by one into the article lead-out passage 15 under their own weight, are arranged in a single file, and are led out of the hopper 11.

In this way, the articles 5 to be sorted in the hopper 11 are floated by the pressure of the pressurized fluid D, and are dropped by their own weight from the article outlet passage 15 to be led out of the hopper. It functions to reduce the gravity of the article 5 by the pressure of the pressurized fluid D. Therefore, when the plurality of articles 5 to be aligned or the articles 5 to be aligned collide with the upper end opening 15a of the article lead-out passage 15, the mechanical impact force applied to the articles 5 to be aligned is reduced. , there is no risk of damaging the articles 5 to be aligned.

Furthermore, since there is no risk of the articles 5 to be aligned being damaged, there is no risk that the outlet passage 15 will be clogged by the damaged articles, and even if a phenomenon that causes clogging occurs, the article outlet passage 15 will not be clogged. Since the pressurized fluid D is injected into the passage 15, the fluid pressure can always eliminate clogging of the articles 5 to be aligned, thereby achieving reliable alignment of the articles 5 to be aligned. I can do it.
